Back there?  Make sure it isn't the distributor drive housing to head joint.  There are no oil pressure galleys in the rear of the head to block joint.  Only at the front drivers side corner.

I'd clean the oil stain with a solvent and run it to see if it's an active leak .  if it's an active leak from the head/block interface, i'd then use the headbolt tightening sequence and go over the headbolts with an accurate torque wrench. clean it again and see if it still leaks.

Thanks jimk. That is helpful. The distributor housing seems dry as do the bolts but I'll look again. Just retorqued head and all bolts were to spec. Motor miles supposedly 17k original miles per the dealer I bought it from but who knows. Exhaust manifold was replaced a year ago and new studs loctited. No oil leak at the studs.

I bought a borescope so i can look back there and figure out whats going on. Thanks for everyone's help. Well im sure i will one day have to replace the head gasket, i have spent a year sealing timing chain cover leaks, manifold leaks ect. Dont feel like removing all that to do the head just yet!

One of the bolts that hold the distributor housing also has a special "sealing" washer. It's the upper bolt on the intake side of the housing. In some cases, I've seen a lock washer installed. On this particular bolt, you don't use a lock washer, otherwise it can leak.
